May 2026 includes several important public holidays and long weekends across Thailand. These dates may affect government offices, immigration services, banks, transport schedules, and business operating hours.
The infographic above highlights the key public holidays taking place throughout May and early June 2026, including important closures and religious observances.
4-Day Long Weekend
Thailand will have a 4-day long weekend from:
- Friday 1st May 2026
- To Monday 4th May 2026
This combines:
- Labour Day
- Coronation Day Weekend
Many residents and tourists are expected to travel during this period, so transport and accommodation may be busier than usual.

Labour Day is a public holiday mainly observed within the labour and industrial sectors.
Some businesses and government offices may close or operate on reduced hours.
Coronation Day – Monday 4th May 2026
Coronation Day is a national public holiday in Thailand commemorating the coronation of the King.
Government offices, banks, and many official services may be closed during this holiday.
Royal Ploughing Ceremony – Wednesday 13th May 2026

This day is primarily a public holiday for government officials and may affect certain public services and office operations.
Visakha Bucha Day – Sunday 31st May 2026

- Some entertainment venues may close temporarily
- Temples and religious sites may be busier than usual
Visakha Bucha Substitution Holiday – Monday 1st June 2026
Because Visakha Bucha Day falls on a Sunday in 2026, a substitute public holiday will take place on Monday 1st June 2026.
This creates an additional 3-day long weekend from:
- Saturday 30th May
- To Monday 1st June 2026
Queen Suthida’s Birthday – Wednesday 3rd June 2026
Queen Suthida’s Birthday is observed as a national public holiday across Thailand.
